LONG BEACH — Police on Monday identified an 18-year-old Long Beach man gunned down over the weekend, and announced the arrest of another local man in connection with the slaying.

The victim was found by patrol officers sent to the 1100 block of Linden Avenue at 11:54 a.m. Sunday, said Lisa Massacani, a Long Beach Police Department spokeswoman.

The teen was found in the southbound lane of Linden, suffering from a gunshot wound to the upper body, and was taken by Long Beach Fire Department paramedics to a local hospital, where he was pronounced dead later that day.

The suspect surrendered to police at about 9 p.m. that night, Massacani said.

He was identified only as a 21-year-old Long Beach man, pending the on-going investigation, Massacani said.

Los Angeles County Coroner's officials identified the victim as Isaac Preciado of Long Beach.

Massacani said it was unknown where the shooting occurred and said the motive for the shooting remained under investigation Monday.

"It is not being investigated as a gang-related crime," she noted.

Anyone with information regarding the killing was urged to call LBPD Homicide Detectives Mark McGuire or Greg Krabbe at 562-570-7244.
